ANIMAL-STANOIIION.

To all, whom it may concern.' Y Be it known that I, JOHN M. B. Lijiwis a citizen of the United States, residing at .Lynchburgin the county of Campbell .and

State of Virginia, have invented certain new and useful Improvements 1n Animal-Stanchions, of'which the following is` a specification. f

My invention relates, to, improvements in animal stanchions. v i

An important Object of the invention is to provide an animal stanchion which will p05- sess-the advantages of the stanchion having only one movable side, and also of the will be free from certain disadvantages encountered in connection withthe same.

A form of animal stanchion now in use, is constructed with a relatively stationary arm, and a movable arm to be shifted to opened and closed position. The` disadvantages encountered in connection :with dthisform of stanchion is that when the swinging arm is moved to the open position, there is a space at the closed side of the stanchion, thus re-` upright post is sufficient for each stall dispensing with the use of the sure stopor go right. However,when a stanchion ofV this vcharacter is Open, it is possible Vfor the cow to easily walk through. the stanchion. This 'type of stanchion isdesirable in Vas .much as it enables the stalls to be constructed ..1arger, giving the cow more room and freedom of movement, and providinga cheaper stall, since the sure stops are dispensed with. However, this type of stanchion is Y objectionable since, as far as I am aware, no

' able arms, connected at their lower ends? Y means has been provided to prevent the cow from walking 'throu hfthe stanchion. y 11n accordance wit my invention, I provide a stanchion embodyingafpair of movp with a member, which is adaptedtomserve as an impediment or? obstruction to prevent the cow from walking throughthe stanchion.

By this means, the advantages of both forms i VVSpecification of Letters latent. I

of, illustration is shown a preferred 'em-V bodiment of my invention, the numeral:10

designates the oppositely arranged arms `or sides of the.'stanchion. These arms are preferably pivoted, at their lower ends, as shown at 11, with a preferably U-shaped impeding element 12. Thisim- .peding element may be formed in any other suitable shape and any othersuitable connection may be providedv between it andthe arms 10. It is thus seen that the arms 10 V'are pivoted to the impeding element 12, and

In the accompanying drawings forming a Fig. 1, the impeding ele# In the drawings, wherein for the purpose mentv 12 will .prevent the cow from walking through the stanchion.

The arms 10 are preferably tubular'and attheir upper ends, receive coupling-plugs 13, held therein by transverse pins 14 or the like. These coupling-plugs. l. are provided with heads 15, having transverse openings 16jreceiving-y a vpreferably longitudinallyl curved transverse support-bar 17. The

outer portions oi' this support-bar are curved in arcs of circles which are concentric with the pivots 11, as shown. Y

The support-bar 17 is Vprovided at a point preferably Veolui-distantly spaced. from the ends thereof with an opening 18, whichis Y preferably formed square in cross section for receiving a squareportion 1915i a suspen-` sion element 20. Above the support-bar '17,'

this suspension element has a shoulder 21, and below it a head 22 is formed byflattening or hammering the end of the portion19.

The suspension element 20 is provided `at its will turn the supporting element 20, where' by the link 24 will cause it transverse portion 27 to ride upon the cani faces `29. As soon as the stanchion is released, these cam faces will automatically return it to the proper transverse position. l Y

The upper link 28 is `provided with a transverse member 30BL and anl opening or notch 30, near and beneath the transverse member 30%- The transverse member 30 is adapted for insertion within a head V31, of an upper supporting member, carried vby a shank 32. The head 31 has ,aoylindrical Y opening 33, having a contracted upper opening 34. When the upperlink 29 is inverted, so that the opening or notch 30 will receive the jaw 35, the transverse portion 302L mayv be inserted within the opening 34, subsequently to which the link 28 is swung downwardly. It is'thus seen that it will be im. possible for the link 28 to be separated Jfrom the head 31 until it is again inverted, but this link is free to partake of restricted swinging movements, longitudinally of the stall.

AThe shank 32 is adapted to be adjustably mounted within an opening 56, formed in a supportblock 37. The shank 32also carries spaced pins 38, for insertion within a groove 39, which is horizontally arranged. The shank 32 may be inserted within the open- .ing 86 when the pins 38 are positioned to enter the groove 39, and the shank 32 is then turned so thatlthese pins assume a vertical position, thereby positively preventing longitudinal displacement of .the shank. The shank however is reeato` partake of slight turningV movement. The support block 37 is secured to a pipe rail 40 by a U-shaped member 41, as shown. When thel rail 40 is notV used, the beam 42 may be subi,ee9,417

istitutedtherefor, (seefllig. 9) and the support block 37 will thenbe equipped with a fiatbase 43 apertured. for receiving bolts 44,'asshown.

Means are provided to shift the arms 10 to' the opened and closed positions, comprising a-lever 45, provided at a point equi-distantly spaced from the ends thereof withy a cylindrical opening 46, '.pivotally receiving a cylindrical portion 47 of the supporting element 20, there beingia flangeA or shoulder 48 above thesame.v The opposite ends of this lever 45 are'apertured 4for receiving pivot elements 49 Vhaving pivotal connection with links 50, the opposite ends of which are pivoted to studs 50', rigidlysecured tothe heads 15. .At one end or the lever'45, there is an extension 51, preferably formed integral therewith, and this extension is equipped with a tubular head 52. This tubular head slidably receives a vertically morable bolt 53, adaptedto enter a vertical opening 54 in Athe transverse support-bar 17. The bolt 53 has a longitudinal slot 55, receiving a transverse pin 56,V which prevents its displacement.

At it lower end, the impeding element 12 i has suitable connection with a chain or flexible anchor velement 57 which is adjustably connected with an anchor device to be now described. This anchor device extends longitudinally oi". the stall and embodies a base plate 58, which is bolted or otherwise rigidly f secured to the ledge 59 of the ioor of the stall.

This base plate is provided at one end with L-shaped members or knuckles 59', A'adapted to receive therebeneath a transverse head GO, formed upon an 'upper bar 61. This up per bar has a series of openings or notches 62, spaced longitudinally of the same, for receiving the lowermost` link of the chain. At its opposite end the base plate 5S is provided with a pair of spaced apertured knuckles 63 receiving a bolt, 64, passing through .a knuckle G5 on the bar 6l. It is thus seen -that the upper and lower connections for the stanchion may be adjusted longitudinally ci' the stall. v

rlhe operation oftheapparatus is as fol` lows: i

lVhen the lever 45 isswung to the position shown in Figs. 1 and 4,' the bolt 53 will enter the opening4 54 and ,the arms 10 will be .locked in a closed position. When it is desired to open the arms 10, the bolt 53 is ele- ;vated fromV within thev opening 54, and may serve as a handle for swinging the lever 45 upon its pivot, to shiftithe' arms 10 to the ropened position. V'When in the open position, as indicated by the dotted lines in Fig.V

l, the impeding element 12 will serve to effectually prevent the cow. fromA walking through the stanchiomwhile the two arms arev swung outwardly su'fciently to close the spaces between the stanchionl and the sides It is to be understood that the form of my"l invention herein shown and described is to l be taken as a preferred example of the same, and that various vchanges in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
